Objective To explore the prevalence and risk factors of knee osteoarthritis (OA) among the elderly in Tianjin. Methods Totally 2038 elderly in Tianjin were investigated from January 2010 to June 2011 according to protocol of APLA-COPCORD Core Questionnaire to identification of risk factors for knee OA. Results The prevalence rates of knee pain and knee OA were 23.1％ and 21.7％,respectively. Knee OA appeared much frequently in women than men (27.6 ％ vs.16.1 ％,x2 =46.893,P＜0.001 ) in the trend of increase with aging(x2 =764.34,P＜0.001).BMI in knee OA group [(25.4±3.3) kg/m2]was significantly higher than in non-knee OA group [(23.8± 2.9) kg/m2],(t =7.944,P＜0.001).Menopause age in female knee OA group was younger than in female non-knee OA group [(50.2±3.7) years vs.(52.8±4.1) years,t=7.665,P＜0.001].Binary logistic regression revealed that age,sex,BMI and age of menopause were risk factors of knee OA,and eating vegetable might prevent from osteoarthritis,whereas there were no significantly association between knee OA and the other factors such as smoking and drinking.Conclusions Age,female and overweight are identified as risk factors of knee OA.

Objective To analyze the characteristics of atherosclerosis in elderly patients with isolated systolic hypertension (ISH) combined with low diastolic blood pressure and risk factors related to low diastolic blood pressure (DBP).Methods A total of 447 elderly patients with untreated ISH were divided into the low DBP (DBP＜70 mmHg, 1 mmHg=0.133 kPa) group (n=206) and the non-low DBP (DBP＞ 70 mmHg) group (n=241) according the DBP level.Clinical data including brachial-ankle pulse wave velocity (baPWV), carotid artery ultrasonography, blood lipids, blood glucose, plasma homocysteine were collected and determined.baPWV, carotid intimal-medial thickness (IMT) and the incidence of carotid plaques were compared between the two groups.Risk factors for low DBP were analyzed.Results There were no significant difference in systolic pressure levels between the low DBP group and the non-low DBP group [(160.8±10.1) mmHg vs.(161.1-±-10.9) mmHg, P＞0.05].Pulse pressure, baPWV levels, IMT and the incidence of carotid artery plaque were higher in the low DBP group than in the non-low DBP group [(98.4 ±11.7) vs.(77.4±12.0) mmHg, (1 785.3±175.0) vs.(1 436.5±114.4), (1.2±0.2) mm vs.(1.1±0.3)mm and 78.2％ (161/206) vs.67.2％ (162/241), each P＜0.05].Stepwise logistic analysis showed that age, gender (female) and diabetes were independent risk factors for low DBP (OR=1.62, 2.07, 1.38, all P＜0.05).Conclusions Atherosclerosis is more serious in elderly patents with ISH combined with low diastolic blood pressure than those without low DBP.Age, gender (female) and diabetes are independent risk factors for low DBP.

Objective To observe the incidence rate of anaemia and analyze the nutritional situation in the elderly population.Methods From April to August 2010,a total of 2052 elderly persons from out-department of Tianjin First Center Hospital were divided into four age groups:65-69years group (n=528),70-74 years group (n=593),75-79 years group (n=423) and 80 years and over group (n= 508).The body mass index (BMI),haemoglobin (Hb),mean corpuscular volume (MCV),triglyceride (TG),creatinine (Cr),serum albumin (ALB) and ferritin (Fer) were tested and evaluated using K-W test.Results (1) Anaemia was found in 90 subjects (4.4 %),4.0% in men and 6.l% in women,9.5% in 80 years and over group.The subjects with Hb level less than 90g/L were all 80 years and over.(2)There were significant differences among the groups in BMI,TG,Cr,ALB,Hb,MCV and Fer levels (all P＜0.01).There were significant differences among four groups in Hb and ALB levels (P＜0.01 ),and partially differences in TG, Cr and MCV levels (P＜0.05).(3)The Hb level was significantly correlated with TG, ALB, Fer and MCV levels (r=0.115,0.211, 0.114 and 0.089, all P＜0.01 ) from Pearson analysis.Conclusions Anemia incidence in elderly population is increased along with aging and is higher in women than in men, especially higher in 80 years and over group.Nutritional situation gets worse with aging.

Glucose-6-phosphate dehydrogenase (G6PD) derives from the expression of the house-keeping gene G6PD. Recent studies have indicated that G6PD is related to tumor genesis, growth, clinical phenotype, therapy, and prognosis. To elucidate the relationship between G6PD and cancer, three siRNA sequences and one negative control sequence were designed based on the 3' noncoding region of the human G6PD gene. Two complementary single-strand DNA (sense and antisense) were designed and synthesized based on siRNA sequences. The DNA fragments were annealed and ligated to the GFP expression vector pRNAT-U6.2/Lenti. One siRNA with higher interference efficiency than the other two was found after siRNA plasmid transfecting human skin A375 melanoma cells. After lentivirus particle packaging and virus production, the A375 cells were infected, and the single cell clone was acquired and cultured to establish the stable cell strain. Western blotting showed that the endogenous G6PD in the stable A375 cell strain was 0.257 ? 0.074, which was 11.17% of G6PD expression (2.301 ? 0.286) in wild type A375 cells. The final siRNA interference efficiency in this stable cell strain was 88.83%. The G6PD activity of A375-G6PD?驻 was 21.53% of A375-WT. Further study showed that A375-G6PD△ doubling generation time prolonged, and its proliferation was greatly inhibited and the cloning efficiency lowered 25%(P

Objective To evaluate the efficacy of medical supervised aerobic exercise on physical activity, quality of life and psychological status in patients with systemic lupus erythematosus (SLE). Methods SLE patients who fulfilled ACR criteria were recruited and divided into 2 groups: exercise group (n=24) and control group (n=25). The patients in the exercise group were supervised to have aerobic exercises. The intensiveness of exercise was determined by 20%-40% of maximum heart rate reservation. Visual analog scale (VAS), SLE disease activity index (SLEDAI) score, physical working capacity (PWC170), SF-36 and profile of mood states (POMS) of the two groups were used to evaluate the changes at the baseline, 1 month, 3 months and 6 months after this study. Results The 2 groups were homogeneous and comparable in disease activity at baseline. 1, 3 and 6 months after the study, the VAS, PWC170, POMS and SF -36 of SLE patients were improved in certain degrees in both groups, while the improvement of VAS (P<0.05), PWCITO (P< 0.01 ) and social function of SF-36 (P<0.05) of exercise group were significantly more evident than those of the control group in 6 months after study without any impact on disease condition. There was a high negative correlation between VAS and 5 categories of POMS (r=-6.26~-0.393, P<0.01 ) and a more relevant positive association between VAS and 2 categories of POMS (r=0.534~0.611, P<0.01). Conclusion The data demonstrate that the supervised aerobic exercise can ameliorate physical capacity, improve quality of life and psychological and emotional status in the state SLE patients without aggravating disease per se.

Objective To find out an effective therapeutic method for and observe whether there is any synergistic action or not between fetal spinal cord transplantation (FST) and methylprednisolone (MP).Methods Fifty male adult SD rats were randomly divided into group A,B,C,D and E,10 in each group.Group A was treated with both large dosage of MP and FST,group B with MP only, grop C with FST only and group D without any treatment.Group E served as blank control.Fetal spinal cord was obtained from 14-day pregnant rats .Spinal cord Somatosensory evoked potential (SSEP) examination and behavior observation were performed in 24 hours and in 8 months after treatment By the way of reduced silver staining, the condition of nerve plerosis and regeneration could be observed.Results There were significant differences in the latent period and amplitude of N1 wave in SSEP between group A and group B,C and D (P＜0.05).No obvious behavior changes were found except partial sensory recovery in the left lower limbs in Group A.Histologically,more nerve fibers contacting with branches at injury area could be found in Group A than in Group B,C and D.Conclusion The combination of large dosage of MP and FST can produce synergistic effect in the recovery of the injured spinal cord.

Objective To evaluate the value of blood coagulation biomarkers in orthopaedic traumatic patients after surgery and analyze its diagnostic values for venous thrombosis embolism.Methods In thiscase control study, we consecutive enrolled 108 traumatic patients after surgery.54 patients have thrombosis and other 54 patients have no thrombosis.Blood was taken 3 -4 days after surgery.Routine coagulation screening test , FDP(fibrinogen/fibrin degradation products) , D dimer and new item such as TM( thrombomodulin) , TAT( thrombin-anti-thrombin complex) , t-PAIC( tissue-type plasminogen activator-plasminogen activator inhibitor complex),PIC(plasmin-anti-plasmin complex) were tested.The difference between groups of these biomarkers was compared, and then the receiver operation curve ( ROC) was drew to determine the diagnostic cut-off point and diagnostic performance.Results ALL blood coagulation biomarkers in orthopaedic traumatic patients after surgery were significantly increased.The group of patients with thrombosis have higher TM(9.04 ±2.06) IU/ml,t-PAIC(10.15 ±4.23) ng/ml, PIC(1.15 ±0.70)μg/ml, D dimer(5.31 ±5.10) ng/ml than group without thrombosis TM(7.50 ±1.70) IU/ml, t-PAIC (6.97 ±2.56)ng/ml, PIC(0.93 ±0.84)μg/ml,D dimer(2.35 ±2.12)ng/ml,and P=0.000 2,<0.000 1,<0.000 1,<0.000 1, respectively.However, TAT(4.79 ±4.32)ng/ml, (6.51 ±5.92)ng/ml, FDP (8.87 ±7.68 )μg/ml, ( 4.91 ±4.67 )μg/ml showed no difference between thrombosis groupand no thrombosis group, (P=0.212 3,0.050 8; respectively).The area under the ROC curve of TM, t-PAIC, PIC and D-dimer were 0.718 5,0.741 6,0.648 0,0.670 0, respectively; P values were <0.000 1,<0.000 1, 0.009 3,0.004 1, respectively; cut-off values were 11.15 IU/ml, 10.65 ng/ml, 1.36 μg/ml, 7.69 ng/ml, respectively;positive likelihood ratios were 9.00,11.29,3.66,14.60, respectively;specificity were 98.15%,96.23%, 90.20%, 97.96%, respectively; the diagnostic rates were 20.3%, 46.3%, 35.8%, 25.9%, respectively.Conclusions There were coagulation and fibrinolysis system activated in orthopaedic traumatic patients after surgery.TM, t-PAIC, PIC, D dimer were good biomarkers for the diagnosis of thrombosis after trauma surgery.TAT was not fit for screening thrombosis after surgery because of influence of anti-coagulation.
